​

Answer 1

Answer:

Find the product using suitable properties: (a) 738 x 103 (b) 854 x102 (c) 258 x 1008 (d) 1005 x168

(a) 738 × 103

= 738 × (100 +3)

= 738 × 100 + 738 × 3

= 73800 + 2214

= 76014

(b) 854 × 102

= 854 × (100 +2)

= 854 × 100 + 854 × 2

= 85400 +1708

=87108

(c) 258 × 1008

= 258 × (1000 +8)

= 258 × 1000 + 258 × 8

= 258000 + 2064

= 260064

(d) 1005 × 168

= (1000 + 5) × 168

= 1000 × 168 + 5 × 168

= 168000 +840

=168840
